planar d-bar integral equation is one of the inverse scattering solution methods for complex problems including inverse conductivity considered in applications such as electrical impedance tomography (eit). recently two different methodologies are considered for the numerical solution of d-bar integrals equation, namely product integrals and multigrid. the first one involves high computational ...

 This paper considers the problem of estimating the population mean Ybar of the study variate Y using information on different parameters such as population mean $(bar{X})$, coefficient of variation $(C_x)$, kurtosis  $beta_{2(x)}$, standard deviation $(S_x)$ of the auxiliary variate x and on the correlation coefficient, $rho$, between the study variate $Y$ and the auxiliary variate $...

We use three examples-field and ecology-based inventories in Costa Rica and Papua New Guinea and a museum and taxonomic-based inventory of the moth family Geometridae-to demonstrate the use of DNA barcoding (a short sequence of the mitochondrial COI gene) in biodiversity inventories, from facilitating workflows of identification of freshly collected specimens from the field, to describing the o...

the aim of this study was to investigate the effect of steam treatment on nutritive value of date (phoenix dactylifera) leaves. date leaves were chopped and mixed with water or sulfuric acid solution to contain 50% moisture with or without 1% sulfuric acid. steam treatment of the date leaves was carried out using three levels of steam pressure (14, 17 and 20 bar), three reaction times (120, 180...

implant-supported craniofacial prostheses are made to restore defective areas in the face and cranium. this clinical report describes a technique for fabrication of an orbital prosthesis with three adjacent implants in the left lateral orbital rim of a 60-year-old woman. selection of appropriate attachment system (individual magnetic abutments versus bar-clip attachment) for implant-supported o...

In this article, we utilise the non-relativistic potential model to calculate mass-spectra of all bottom [ $$bb][{\bar{b}}{\bar{b}}$$ ] and heavy-light $$bq][{\bar{b}}{\bar{q}}$$ (q = u,d) tetraquark states in diquark–antidiquark approximation. The four-body problem is reduced into two body by numerically solving $$Schr\ddot{o}dinger$$ equation using a Cornell-inspired along with relativistic c...

This paper proposes a method to autonomously extract stable visual landmarks from sensory data. Given a 2D occupancy map, a mobile robot rst extracts vertical line features which are distinct and on vertical planar surfaces, because they are expected to be observed reliably from various viewpoints. Since the feature information such as the position and the length includes uncertainties due to e...
